Hamsters are a general name for all hamsters, but different rats have their names, and in China there are probably three sevens. Because both sides of the hamster's cheeks are very food-filled and can be used to carry and store them, they are named hamsters.
One of the most basic reasons for hamster hair loss is that hamsters are seasonally hairless, twice a year, because hamsters are clean, they clean their hair regularly, they strip their hair and grow new ones are good for hamsters, they clean it more when they lose hair, they keep it clean, otherwise hamsters are hard to bear when hamsters are allergic, and when hamsters are allergic, they are hairless. Food needs to be looked at in some places, like it can't drink raw water, drink it up, which is too soft for hamsters.
Heated in winter, or it freezes to death by accident, and the Internet gives us a little knowledge, which means that in winter, if your hamster suddenly dies, it's not dead, it can be used to turn on the hot wind until it moves. It cannot be given water to bathe, which can easily cause hamsters to become skin sick and then die, and can be washed with bath sand, which is, in fact, more sophisticated, with a lot of things being noticed, or its little life being buried without being careful.
The hamster is also tenacious, and no one is allowed to invade its territory, or else it will attack it, so when feeding it, be careful to be bitten by it, its teeth are sharp, it can break easily, and if broken, it's better to disinfect it with alcohol, or it's more troublesome to be infected with bacteria. Do not feed hamsters with food of unknown origin, eat it badly, and eat it only regularly.
